I hear about Omote and Ura Shiho Nage all the time. But does anyone know, or has anyone heard of, "straightline" Shiho nage??? Probably not since it's not well known. "Straightline" Shiho nage has no omote or ura movement. My students love to do SL esp when they go to seminars. Messes a lot of people up and makes them wonder where it came from. One of my favorite techniques too.
